How to Use Pacifist to Replace Deleted or Missing OS X Components
Insert the OS X Installer DVD into the optical drive. Use a simple utility like TinkerTool to toggle invisibility so you can see invisible items. Alternatively, open the Terminal application in your Utilities folder and at the prompt enter the following:
defaults write com.apple.finder AppleShowAllFiles Yes
Press RETURN.
To turn off the display of invisible files repeat the above command substituting No for Yes.
The install packages are located in the /System/Installation/ folder on the DVD.
Download the shareware utility Pacifist from VersionTracker or MacUpdate. Use it to extract a fresh copy of the missing item(s) from the file archives on your OS X installation DVD. The file archives are in the /System/Installations/ folder (use Go to Folder option in the Go menu of the Finder.)
